A John McCain Quote We Need to Ask Him About

Digby has linked to this, and it's a powerful statement written by John McCain some years ago in a forward to a book about the Vietnam War. Check it out:

It was a shameful thing to ask men to suffer and die, to persevere through god-awful afflictions and heartache, to endure the dehumanizing experiences that are unavoidable in combat, for a cause that the country wouldn’t support over time and that our leaders so wrongly believed could be achieved at a smaller cost than our enemy was prepared to make us pay. No other national endeavor requires as much unshakable resolve as war. If the nation and the government lack that resolve, it is criminal to expect men in the field to carry it alone.

Does it sound like any conflict we're involved in now?
